PS3 version DLC on the Vita?

Since Disgaea 3 first came out on the PS3, there has been a ton of DLC. Furthermore, they have added most of it all together in a complete package, which I bought, as it was cheaper and I hadn't purchased any single DLCs.

That said, my question is as follows: Is it thinkable or likely that they will port the PS3 DLC to the Vita?Or would I have to rebuy it?Or is it already included in the Vita version?
